Description
Technical field
The present invention relates to environment-friendly building materials fields, specifically, being a kind of to prepare non-burning brick match using phosphate ore flotation tailings
Side and method.
Background technology
The waste generated during the tangible flotation of phosphate rock of tailing, due to carbonate containing height, it is difficult to be used for building materials, chemical method
Do not have economic benefit using current technology, and easily cause secondary pollution, therefore phosphorus tailing cannot be effectively treated for a long time.
Stockpiling does not only take up tract, loss is wherein a large amount of to tailings stack after phosphorus tailing is emitted into Tailings Dam or dehydration mostly
Useful composition also causes serious influence to the ecological environment of surrounding:Most of tailing is all phosphorite after inorganic acid acidolysis
By-product, and when chemical transport occurs for certain transportable elements in tailing, can also cause serious dirt to air and water and soil
Dye.Currently, contaminated area is up to million mu caused by tailing in China, therefore, carry out the comprehensive utilizating research of phosphorite tailings, to phosphorus
Mine Mineral Processing Industry and ever-expanding flotation of phosphate rock production scale reduce investment, ensure Mine Safety in Production, protect mining tailing wasteland
Ecological environment is of great immediate significance.
It, should in terms of the technical research of phosphate ore flotation tailings comprehensive utilization at present is concentrated mainly on chemical recovering method associated resources
Technical solution because it is of high cost, easily cause secondary pollution, therefore promotion effect is undesirable.Exempt from using phosphate ore flotation tailings preparation
In terms of baking bricks, since phosphate reverse flotation de-magging tailing is compared with other such as flyash, gangue, metal tailings, clinker tailings
Carbonate content is significantly higher, and silicate content is very low, gives making the non-burning brick exceptional hardship brought(It is mainly manifested in intensity not
High, easy to crack, easy decortication etc.), in addition fineness is thinner, and it is more preferably additional that this causes phosphate ore flotation tailings to make non-burning brick needs
Agent, material proportion and technology requirement.This, which allows for technology, does not have key breakthrough, and the present invention is by a variety of exciting agents of addition and admittedly
Agent overcomes these defects, reaches 50% or more in tailing adding proportion, can still prepare and reach the unburned of MU15 standards
Brick is finally realized and is efficiently used.
Invention content

The technical solution adopted in the present invention is:
A method of it is prepared non-burning brick, comprised the steps of with phosphate ore flotation tailings:
(1)Exciting agent and quick lime pretreatment is added to tailing;
(2)To step(1)Material in addition cement and curing agent stir evenly;
(3)To step(2)Material in be added sand stir to get uniform muddy mixture;
(4)By step(3)Mixed material be packed into standard module through pressure or vibration moulding;
(5)By step(4)Product place 24 hours after demould, maintenance at least surrounding obtain it is non-burning brick.
The technical solution adopted in the present invention further includes:
A method of it prepares non-burning brick, comprises the steps of using phosphate ore flotation tailings and another kind waste residue X as raw material:
1)Exciting agent and quick lime pretreatment are added into tailing another kind waste residue;
2)To step 1)Material in addition cement and curing agent stir evenly;
3)To step 2)Material in be added sand stir to get uniform muddy mixture;
4)By step 3)Mixed material be packed into standard module through pressure or vibration moulding;
5)By step 4)Product place 24 hours after demould, maintenance at least surrounding obtain it is non-burning brick.
Further, a method of prepared non-burning brick, mainly organized as tailing, sand, water with phosphate ore flotation tailings
Mud, quick lime, exciting agent and curing agent, by weight percentage, tailing 50%~65%, sand 15%~30%, cement
8%~15%, quick lime 1%~3%, exciting agent 0.1%~0.2%, curing agent 0.1~0.2%.
Further, the step 1)Middle tailing is the tailing of phosphate reverse flotation decarburization hydrochlorate, and essential mineral group becomes white
Marble, collophane, quartz, feldspar etc., wherein dolomite account for 70-80%, and collophane accounts for 7-11%, quartzy 3-5%, remaining is quartz
And feldspar;The tailing fineness is that -0.074mm accounts for 80%, and -0.038mm accounts for 50%.
Further, the step 1)Middle tailing is the tailing of phosphate reverse flotation decarburization hydrochlorate, and primary chemical group becomes:
P2O5Content 5-8%, content of MgO 15-18%, SiO2Content 6-9%.
Further, the step 1)Described in exciting agent be iron chloride, sodium carbonate, sodium sulphate, sodium hydroxide, ammonium acetate
One or more of sulfosalt.
Further, the step 2)Described in cement be plain edition portland cement or composite silica acid salt cement, mark
Numbers 42.5.
Further, the step 2)Described in curing agent be aluminum sulfate, ferric sulfate, sodium phosphate, in waterglass, lignin
Sulfoacid calcium, the one or more of sodium lignin sulfonate.
Further, the step 3)Described in sand grain size be 1-2mm.
Further, the step 4)Maintenance is water seasoning, and daily one, to twice, waters to non-burning brick surface to unburned
